SR&RL rail weights, information from 1916, but weights probably did not change too much after then (before that is not a simple answer); Farmington – Strong – Phillips weights varied from 50 – 52 – 56 & 58 1/4 lbs (most of it 10.48 mi. was 52lb). Phillips to Madrid Jct. 50 lb rail laid in 1919 Almost everything else was 35 lb rail (there were a few small exceptions, but the mileage was very minor). Things like the Mt. Abram branch had .16 mi of 30 lb rail in iron (only the best of nitpickers could point this out on a layout ;^) ). At time of abandonment, there was a reported 2 mi. of 60 lb rail. Information gleaned from Jones, Two Feet Between the Rails

The nominal equivalents for rail weights per the various Code rail sizes in 1:48 scale are as follows:
